test fire button

Is there anyway so that when I hit the test fire button on the V6 for the on-camera flash (with is running TTL pass thought) to NOT fire. Every-time I do this, the on-camera flash fires at 100%


  • You cannot deactivate the test button.

    Thank you.

  • How about switching off the on-camera flash while you press the Test button? v=P
